Im looking for some info on a complete street evo set up. Im coming from an srt-4 so im a little new some of this stuff. 06 Evo ix ...I would like to make in the area of 425, and have a nasty powerband since it will be used mainly on the street. I would like to stay as cost effective as possible but im most definitly willing to spend the cash on a better part to by pass a head ache later on...

Turbo: Stock ix turbo with avc-r
Exh: BR 3" Turbo back and ported/coated o2 housing and manifold
FMIC: ETS 3.5" kit(pipes as well)
BOV: Stock ix
Intake: BR Ported Intak mani, BR Intake, and BR ported TB
Fuel: 780cc inj and walbro 255 fp
ECU: Re-Flash
Drivetrain: Clutch? Tranny?
Suspension: ?

Questions:
-I dont know what type of clutch would be best? Im coming from a FWD to a AWD for a reason, what clutch would be best to handle whatevers thrown at it under 500tq?
-Also, i would really like to rebuild the tranny to a 5 speed since i have read 4th some times falls on its face, as well as its not as strong as a 5 speed. Shep? Bushwacker? If i could buy it, build it, install it, or modify it to by pass any future problems then i would like to do it now. Transfer case?
-Re flash? This is a dumb question(im fore warning you) whats the best one out there? I got the whole tactrix cable thing but whats the best reflash/tuner to go with as far as the email tunes? jestr, melon, ect?
-Suspension, i will not spend the money on coil overs, just not in the budget and i dont see the need for them. But is there any "cheaper" suspension upgrades to help the feel of the car on the street and over all driveability? Shifter bushings? Front sway? ect
-Power wise, im assuming on a e-85 tune that this would put me in the 400hsp range/350tq? About right?
-Should i add head studs and a thicker head gasket?
-Should I add a stronger internal wastegate(i.e. the BR one)?

Mainly the car will be driven on the interstate(roll races), and maybe once a month to the track for 3 or 4 launches.

 

I think your numbers will be hard to achieve with a stock turbo. The FP red or green should get there on e85.
On the e85 note if your going there get bigger injectors.


Answers:
1) Pretty much all clutches will handle your torque number but feel is really just a matter of preference. Some people think my 6 puck ACT is a light switch but I find it quite nice. Others wont touch anything but a twin disk so i guess the choice is yours. Before people say it yes i have heard of the lock out problem but i still haven't experienced it even up to the 7800 rpm limiter i'm running.

2) You can't "rebuild" a 6 speed into a 5 speed but you can swap them. Good luck with that thought people want those 5 speeds. Transfer cases can be hardened up with beefy components but honestly for the transmission and transfer case i'll wait until i break it first.

3) "Best" is such an over used word. Mellon is raved about, 4WS, Jester, hey the choices are out there you should just call one up and see how you feel about them.

4) Feel of the car probably will be bushings for cheap. Go with stock if your going to track the car then upgrade later once you feel your at the limit of the suspension and not your skill.

5) E85 makes awesome power even on stock but i still think you'll have trouble reaching the magic 400whp mark on a stock turbo close perhaps always can just try and see how far you will go.

6) I'll assume you want to run like 30psi on the block so it wouldn't be a bad idea to get head studs but the gasket is fine.

7) No wastegate save up for something else.

 

Wow thank you. Would you add anything else in? Maybe i should just buy a 05 VIII, they made a mr in those, correct? The tranny is probably one of my biggest concerns, build for the worst hope for the best, you know?

I have researched greens and reds(slightly) but i thought the 9 turbo could do it. So I guess just run a VIII with the 10.5 hot side or else a green. The greens have produced up to??? And ran ??? in the quarter? I would assume 450ish and on a decent tune/launch 11.3'ish @ 122....maybe?

 

green or red would be killer on e85... like roadspike said 780cc are not going to cut it with e85... you all most half to double the fuel to run it... im running 1600cc in a gt35r dsm at 90% duty cycle... cams would also be a good investment

 

I always thought cams = needed on VIII....cams = not needed on a IX because of the mivec technology.

 

Cams are still recommended on the 9 people have gotten good results with things like the cosworth m2's and so forth. I'm willing to bet which ever tuner you use will have a recommendation for you.

I say you should go with a Red/Green because your not a fully built car. The cars making big numbers on stock turbos as far as i know have been very tricked out fully built motors with heads and cams pushing the limit of that tiny turbo.

Its just going to be easier to achieve 425whp on a red then it will be on a stock turbo. I'm also not sure how well the stock bov is going to hold up against the typical 30psi tune on e85. I suspect its going to leak at that level, talk to your tuner for his recommendation.

 

Then what would be a good BOV to get? I have run vent to atmosphere on dsm's before and they suck(we all know this)...I dont really care about sound, whats the best bov to hold 30 psi? I have an hks on my srt but usually those are vent to atmosphere....

Isnt the green smaller than the red? What size compressor wheels/spool up time/and trims are each of those turbos?

 

my suggestions in bold and add some cosworth M2 cams for your 9

 

Yes the green is smaller than the red but the red is still going to spool up around 3800 rpm thats plenty fast imo.

 

Not sure what "needed" refers to, but the upgrade from the 256/260 cams of the mivec to the 272 Cosworths was substantial. These cams make good power on 91, and awesome power on 93,100.

 

what ever you do get rid of the stock BOV it will break when you get more hp you can recurculate it until you get big power so you dont loose pressure get a good clutch and a stand alone ecu and maybe half shafts and diffs. before you go big do your research and back up what you think will break before it does cause it will
